  • Two supporting beams 14 extending horizontally so as to be perpendicular to the horizontal foundation beams 12 are disposed so as to span across the two foundation horizontal beams 12.
  • Suspended posts 16 are each connected to first and second end portions of each of the supporting beams 14 by means of third metal connecting fittings (third clamping members) 15.
  • a total of four suspended posts 16 are each disposed vertically inside the hoistway 1.
  • the suspended posts 16 are supported by the horizontal foundation beams 12 through the supporting beams 14.
  • a scaffolding supporting frame includes: the foundation posts 6, the metal supporting fitting 7, the diagonal foundation members 8, the first metal connecting fittings 9, the pins 10, the metal contacting fittings 11, the horizontal foundation beams 12, the second metal connecting fittings 13, the supporting beams 14, the third metal connecting fittings 15, and the suspended posts 16. Furthermore, the scaffolding supporting frame is installed so as to project inside the hoistway 1 from the landing.
  • a lower portion work platform 17 is supported below the horizontal foundation beams 12 by the suspended posts 16.
  • the lower portion work platform 17 has: two lower portion bearing beams 18 disposed horizontally between lower end portions of front and rear suspended posts 16; and a plurality of lower portion scaffolding boards 19 disposed so as to span the two lower portion bearing beams 18.
  • the lower portion bearing beams 18 are connected to the suspended posts 16 by fourth metal connecting fittings (fourth clamping members) 20.
  • the lower portion scaffolding boards 19 are fixed to the lower portion bearing beams 18 by fasteners such as rubber bands, ropes, etc.
  • the lower portion work platform 17 is installed within a range of height dimensions of the landing entrance 2 such that movement from the landing platform 5 is possible.
  • An upper portion work platform 21 is supported above the horizontal foundation beams 12 by the suspended posts 16.
  • the upper portion work platform 21 has: two upper portion bearing beams 22 disposed horizontally between a vicinity of upper end portions of the front and rear suspended posts 16; and a plurality of upper portion scaffolding boards 23 disposed so as to span the two upper portion bearing beams 22.
  • the upper portion bearing beams 22 are connected to the suspended posts 16byfifthmetal connecting fittings (fifth clamping members) 24.
  • the upper portion scaffolding boards 23 are fixed to the upper portion bearing beams 22 by fasteners 25 such as rubber bands, ropes, etc.
  • the foundation posts 6, the diagonal foundation members 8, the horizontal foundation beams 12, the supporting beams 14, the suspended posts 16, the lower portion bearing beams 18, and the upper portion bearing beams 22 may be constituted by steel pipes, for example.
  • the lower portion scaffolding boards 19 and the upper portion scaffolding boards 23 may be constituted by wooden planks, for example.
  • a worker In a work scaffolding apparatus of this kind, if performing work at a top portion inside the hoistway 1, a worker first moves from the landing onto the lower portion work platform 17, then moves onto the upper portion work platform 21 from on top of the lower portion work platform 17. It is possible to move from the lower portion work platform 17 onto the upper portion work platform 21 using a pedestal, or a ladder, etc., before mounting a portion of the upper portion scaffolding boards 23, for example.
  • the work can be performed using only the lower portion work platform 17 without mounting the upper portion work platform 21.
  • a distance from the lower portion work platform 17 to the upper portion work platform 21 is set within a range enabling mounting of the upper portion work platform 21 to be performed by a worker on the lower portion work platform 17 to facilitate assembly of the work scaffolding apparatus.
  • the vertical mounting position of the upper portion work platform 21 is also desirable for the vertical mounting position of the upper portion work platform 21 to be made adjustable. In this manner, it is possible to adapt easily to changes in height from the landing platform 5 of the uppermost floor to the hoistway ceiling portion 1e.
